Professional Surface Finishing Solutions
Precision Zinc Plating & Metal Treatment Services

In modern manufacturing, surface finishing is not just a process —
it is a critical function that defines product durability, consistency, and long-term performance.

We provide professional zinc plating and surface treatment services designed to meet the demands of precision manufacturing, tooling, automotive, and industrial components.

Our Capabilities
Alkaline Zinc Plating (Blue Passivation)
• Uniform coating thickness
• Excellent adhesion
• Enhanced corrosion resistance
• Stable appearance across batches

Our controlled alkaline zinc process ensures consistent quality, even for complex geometries and tight tolerance components.

Why Our Process Matters
✔ Controlled Pre-Treatment
Multi-stage cleaning and electrolytic activation ensure optimal surface preparation before plating.
✔ Stable Plating Conditions
Current, temperature, chemistry, and filtration are strictly controlled to deliver repeatable results.
✔ Improved Corrosion Performance
Blue chromate passivation enhances corrosion resistance while maintaining a clean, professional finish.
✔ Process-Oriented Quality Control

We focus on process stability, not just final appearance — reducing rework, failures, and downstream issues.

Who We Serve
• Precision machining factories
• Automotive & electronic component manufacturers
• Tooling and mould makers
• Metal fabrication workshops
• Manufacturers planning to internalize surface finishing processes

More Than a Subcontractor , We don’t just plate parts. We help manufacturers solve surface finishing challenges, shorten lead times, and improve production reliability.

If you are planning to:
Improve plating consistency
Reduce dependency on unstable subcontracting Or build a more controllable finishing solution

👉 We welcome in-depth technical discussions and on-site collaboration.

为什么"马来西亚"顾客现在会开始要求 Black Nickel?经过了研究,配合趋势,得出大概一个结论 -
这不是市场突然“跟风,而是产品需求真的变了。

这两年,越来越多客户开始指定:
👉 Black Nickel(黑镍)
很多加工厂一开始都会愣一下:

以前没怎么听过,怎么突然这么多人要?

其实原因很现实。
① 外观需求升级了
现在很多零件,已经不只是“能用”,
而是要:深色、低反光质感统一
看起来“高级、不廉价”
Black Nickel 的颜色不是死黑,
而是偏深灰黑、金属感,
比黑锌、黑铬更柔和,
设计感更强。
所以你会发现:
电子、机械外壳、精密件、装饰件,
越来越多人开始选它。

② 黑锌、黑铬开始被比较了
以前常见选择是:
黑锌(便宜,但颜色不稳定)
黑铬(外观好,但成本高、工艺限制多)
Black Nickel 刚好卡在中间:
✔ 外观比黑锌稳
✔ 工艺弹性比黑铬高
✔ 成本相对可控
客户自然会开始问。

③ 客户开始“懂一点表面处理”了
现在的客户,不再只是丢图、等报价。
他们会问:
会不会掉色?
表面会不会太亮?
能不能统一批次颜色?
Black Nickel 的特性,刚好能满足这种**“不想太高调,但要质感”的需求。**

④ 不是突然流行,是“被逼升级”
说穿了,
这不是电镀厂推出来的工艺,
而是产品设计、市场竞争逼出来的选择。
当客户开始在外观、质感、品牌感上竞争,
表面处理,自然就会升级。

简单一句话总结
Black Nickel 不是新工艺,
只是现在,终于轮到它被需要。

如果刚好你也有接触 Black Nickel 欢迎我们来私下交流 😊😊

🔧【为什么氧化件一定要先完全 Stripping 才能重新氧化?】
很多客户会问:
“这件产品外观不满意,可以直接再做一次阳极氧化吗?”
答案是:不可以。

如图所示(左:重新氧化后的正确效果;右:未完全 Stripping 就直接氧化的失败案例),
表面会出现:
色差明显
斑驳、发灰、发暗
氧化层不均匀
粗糙、脏污无法覆盖
---
🧪 原理说明:
阳极氧化(Anodizing)需要铝材表面是完全干净、纯净、裸铝状态。
如果表面残留旧的氧化层,即便只是很薄的一层,也会导致:
1️⃣ 新氧化层无法均匀生长
旧膜阻挡电流,使膜层厚薄不一致。
2️⃣ 化学反应受阻,导致上色不均
特别是染色阳极,色差会非常明显。
3️⃣ 不良外观无法靠“二次氧化”掩盖
旧膜上的瑕疵会放大,变得更糟糕。
因此必须进行 Stripping(化学退膜)
👉 把旧的膜层彻底、均匀地去除
👉 让铝材回到“原始金属”的状态
👉 才能重新进行完整的阳极氧化流程

---
📌 总结:
要得到稳定、漂亮、均匀的阳极氧化效果,
第一步永远是完整 Stripping。
直接重复氧化只会让外观更糟,甚至报废。

如图左侧就是正确流程处理后的效果,
右侧则是未经退膜直接氧化所造成的缺陷。
